A spectrum
of models of various complexity is used in modelling the natural Earth
system. Depending on the nature of questions asked and the pertinent time
scales, there are, on the one extreme, conceptual, more inductive
models, and, on the other extreme, three-dimensional comprehensive models
operating at the highest spatial and temporal resolution currently feasible.
Models of intermediate complexity bridge the gap. The EMIC network
is supported byGAIM
(Global Analysis Integration and Modelling), an IGBP
(International Geosphere-Biosphere Program) task forceand by the
participating institutes (see table of EMICs).
